No. 2 alyssa has some coins in her purse consisting of pennies, nickels and dimes. She has 2 more nickels than dimes and thrice as many pennies as nickels. If the total is 0.52 dollars how many coins of each kind does she have.
Answered by Reiny
number of dimes --- x
number of nickels --- x+2
number of pennies --- 3(x+2)

now considering value of these coins:

10x + 5(x+2) + 1(3)(x+2) = 52

take over
Answered by Kevin Kirkpatrick
10x+5(x+2)+1(3)(x+2)=52
10x+5x+10+3(x+2)=52
10x+5x+10+3x+6=52
18x+16=52
18x=36
x=2
2 dimes
4 nickels
12 pennies
